interlaminar 缺点是在是的合成管子广泛地在石油和化学工业使用了的金属层的损坏的一种主要形式。在这份报纸，一个 Stoneley 波浪方法被介绍在把压成薄片的管子结构检测 interlaminar 损坏。Stoneley 波浪拥有一些好特征，例如在接口的高精力和大排水量并且在非散高周波，检测 interlaminar 损坏的敏感能因此被改进，更高的频率能与兰姆波浪相比在损坏察觉被使用。作为频率增加，另外， Stoneley 波浪的波长减少。因此，它在接口检测小缺点的能力被提高。金属层的有限元素模型有 interlaminar 损坏的合成管子被用来分别地模仿兰姆波浪和 Stoneley 波浪的波浪繁殖。损坏地点被使用从有限元素模型获得的 Stoneley 波浪信号计算，然后结果与实际损坏地点相比。模拟例子证明 Stoneley 波浪方法罐头更好与兰姆波浪相比在把压成薄片的管子结构识别 interlaminar 损坏。

英文摘要：

The interlaminar defect is a major form of damage in metal layer composite pipes which are widely used in petroleum and chemical industry. In this paper, a Stoneley wave method is presented to detect interlaminar damage in laminated pipe structure. Stoneley wave possesses some good characteristics, such as high energy and large displacement at the interface and non-dispersive in the high-frequency, so the sensitivity of detecting interlaminar damage can be improved and the higher frequency can be used in damage detection compared with Lamb waves. Additionally, as the frequency increases, the wavelength of the Stoneley wave reduces. Thus, its ability to detect small defects at the interface is enhanced. Finite element model of metal layer composite pipe with interlaminar damage is used to simulate wave propagation of Lamb waves and Stoneley wave, respectively. The damage location is calculated by using the Stoneley wave signal obtained from finite element model, and then the results are compared with the actual damage locations. The simulation examples demonstrate that the Stoneley wave method can better identify the interlaminar damage in laminated pipe structure compared with Lamb waves.
